GAS-BURNER IGNITEB.

Applicationzflled July 14, 1928. Serial Nth-122,290.

This inventionrelates to gas burners and. burner igniters asused inconnection with gas stoves of conventional type.

The control cocks of such stoves, even if originally tight, becomeloosened by repeated use, and in any case are subject to being easilyopened, carelessly or inadvertently by children, contact of clothing andother causes, leading not only to waste of gas, but developing a highlydangerous mixture of the escaping gas with the atmosphere of a room,causing possible asphyxiation, explosion and concomitant effects whichare well known.

In ordinary gas stoves having a plurality of burners, a constantly litpilot is employed for the sole purpose of producing an igniting flame,increased at will by a separate valve,

whereby any selected burner may be ignited,

and such operation not infrequently acts to extinguish the pilot flamebut does not close ofi an insiduous small although constant issue ofgas.

One of the advantages of the present invention is in the provision ofmeans operable automatically to ignite any or all of a'series of burnersthrough which gas escapes, either ac.- cidentally or intentionally, thelighting action being instantaneous.

A further feature is to utilize the otherwise wasted heat of the pilotas a simmerer or other constant source of moderate warmth.

Another purpose is in the production of a device having the foregoingadvantages for the ordinary pilot burner without any change being madeto the other burners whatever, being in effect an attachment.

Other advantages, such as adjustability, ease of installation and adecided saving in gas consumed, are attained by the novel constructionand combination of parts. hereinafter described and shown in theaccompanying drawings, constituting a component of this disclosure, andin which Figure 1 is a top plan View of an embodiment of the inventionas arranged for operation.

Figure 15 is a fra entar ers ectivc view of the combustio d hamb n pStated in general terms the device is comprised of a chamber removablyengaged over a fixed pilot burner of the Bunsen type and connected withthe upper end of the chamber is a plurally'ported casing into which leadconductors extending over the adjacent openings of the several burnersof the stove.

The pilot is supplied with gas delivered fromthe usual header or burnersupply pipe through a nipple 15, the same having a I8- duced end 16threaded to suit an opening in the pipe, the nipple being provided witha large longitudinal bore 17 into which is slidably engaged a tube 18.

The outer end of the nipple, which may be hexagonal, is screw threadedto receive a cap nut 19 bored to permit passage of the tube 18 andcontaining an interior conical seat to receive'a packing ring 20 formedwith a double cone, the other of which extends into a similar seat inthe end of the nipple, this device able on the stem is a snug fittingsleeve 25 having openings 26 by which the admission of air to the burnerstem is controlled,

The upper portion of the stem 24 loosely fits within a burner body 27having a raised central boss 28 through which is a bore in register withthe bore of. the stem and at which point the escaping mixture of air andgas is ignited.

The burner body is rigidly fixed at its base in a plate 29 forming the.bottom of a cylindrical chamber 30. The plate 29 has a plurality oferforations 31 andat one side has riveted to 1t a bracket 32 presentingforks 33 adapted to straddle .the tube 18 at the down-turned angularelement of its bent portion 21.

Adjustable on the forks 33 is aclip 34 provided with a clamp screw 35,the clip resting on the tube, as best seen in Figure 4, in such manneras to support the chamber 30, in combination with the stem 24, atdifferent heights on the stem, the chamber being readily removable fromthe stem and tube by merely raising it.

The open top of the chamber has sheared in its walls a pair ofdiametrally opposite slots 36 from which radial lugs 37 extend,-

these lu s freel engaging in appropriate slots forihed cen i'ally in thewidth of a band 38 encircling the chamber 30 and provided with clampingmeans 39. I

A plurality of plates 40, one for each of the stove burners, are bent toconform to the radius of the chamber 30 and disposed interj acentlywithin the clamp band 38 so as to be held rigid. I I

An outwardly extending flange 41 connects an offset arcuate member '42of larger radius than the plate 40 and formed integrally with the member42 is a polygonal tube 43 constituting a socket and providedwith a setscrew Slidably adjustable in the socket isanother tube 45 shaped at itsouter end to present an inclined flanged partial cover 46 over anopening 47 in its bottom wall, this opening being, in practice, disposedin proximity over the nearest openings in the several stove burners,

the device as a whole constituting a collector.

- positive, thus assuring ignition of any of the It is to be noted thatthe foregoing arrangement provides for considerable variation in thedistances of the stove burners from a central point, represented by theBunsen pilot burner 28, and also differences in angular positions due tothe band 38 clamping the plates when in adjustment.

, Positioned on top of the chamber 30 is a.

gas directional unit of slightly larger diam eter consisting of two indetail in Figure'9.

The lower part cons1sts'ofa metal plate 50 in which are triangularopenings 51, the r main parts as shown the edges of the plate 50 andextending inwardly therefrom are converging flanges 55 meeting at theirinner ends and forming walls enclosing spaces accessible through thetriangular openings 51.

An upper or cover plate 56 isrovided with a down-turned edge 57 somew atexceeding the diameter of the flanges 54 except at two opposed pointswhere projections 58 are formed to extend within the openings betweenthe flanges 55, closely in contact with the flanges 54, serving tomaintain the plate 56 in fixed relation to the bottom plate 50.

The top plate 56 is sheared to produce openings 59 disposed radiallyover the spaces between adjacent flanges 55 and the tongues 60, formedby shearing, are bent at an angle downwardly to extend into these spacesto about half their heights, these tongues acting as deflectorsintercepting a portion of an incoming stream of gas through the tubes 4543, being disposed directly in front at a spaced distance from theirentry and within the unit. In operation when it is desired to ignite anyof the stove burners, indicated at X in Figure 1, the corresponding-cockis opened permiting gas to escape through the burner openings, part ofwhich entering the overlying opening 47 being conducted through thetubes 45 and 43, to the space 61 in the upper unit.

Here'a portion of the stream is directed upwardly through the opening 59and another part. passes over or through the central open ing 53 tobecome ignited by the constantly lit flame of the Bunsen pilot burner28.

When. this occurs a stream of flame ensues which is reconducted back tothe stove burner X causing ignition of all of the several burneropenings therein. Obviously this action is instantaneous and tical useof for. simmerin and like cooking operations of heat, thus ma ing use ofthe gas consumed by it economical. j
